NAIL-DRIVER.

Specification of Letters Patent.

Patented Jan. 31, 1911.

Application filed August 26, 1909. Serial No. 514,768.

To all whom 'it may concern: Be it known that I, MrRoN DionsoN, citiyzen of the United States, residing at Martinsville, in the county ofMorgan and State of Indiana, have invented certain new and usefulIn'iprovements in Nail-Drivers, of which the following is aspecification, reference being had therein to the accompanyingdrzftwing.

This invention relates to hand implements for driving nails, and aims toprovide an improved tool for this purpose of the magazine type, whichwill be of compact construction for convenient handling and manipulationin use.

Important novel features of the invention reside in the particularconstruction and arrangement of the magazine together with special meansfor controlling the feeding of the nails therefrom to the deliverynozzle of the device.

Another important characteristic of the invention resides in the specialconstruction and connection of the parts to facilitate the use ofdifferent driving plunger heads, delivery nozzles and differentcontainer 'tubes to make thedevice applicable to 'the -driving of nailsvarying in size and form.

The invention, with other objects and advantages thereof, and theparticular construction, combination and arrangement of parts comprisingthe same will be apparent from the detail description, hereinaftercontained, when considered in connection with the accompanying drawingsforming part hereof and illustrating one emboc'liment thereof.

In the drawings: Figure l is a longitudinal sectional view of a deviceconstructed in accordance with the present invention. Fig. 2 is a Viewsimilar to Fig. 1 of the lower portion of the device on an enlargedscale, the plunger being removed, Fig. 3 is a transverse section takenon the line 3-3 of Fig. l and looking in the direction of the arrow,Fig. t is a detailed View showing in top plan the cap at the upper endof the casing, Fig. 5 is a detailed view of the feed controlling device,F 6 is a detailed view of the lower portion of the plunger, Fig'. 7 is afragmentary longitudinal section on an enlarged scale, Fig. 8 is atransverse section taken on the line S-S of Fig. 7 and looking in thedirection of the arrow, Fig. 9 is a longitudinal section of a modifiedform.- Referring to the drawings in detail, 1

designates a casing or shell provided at one end with a contracted lowerend portion 2 located centrally of which is a delivery nozzle 3.Extending centrally and longitudinally of the easing is a tubular guide4L for a driving plunger 5, provided with a head 6, which is constructedto enter and work nicely through the delivery nozzle to drive the nailstherefrom, said tubular guide 4L being arranged tudinal alinement withthe delivery nozzle.

7, 8 and 9 designate separate groups of container tubes constituting themagazine of the tool. These groups of container tubes are arrangedwithin the casing around the plunger guide 4, each group comprising anumber of tubes arranged in circular series xedly supported in thecasing, and a feed tube l0 arranged for rotation centrally of eachseries of tubes, said feed tube having at its lower end a side opening11 adapted to be brought into alinement separately with outlet openings12 at the lower ends of the container tubes, said tubes being providedwith walls 13 adjacent their outlet openings 12 inclined toward the feedtube, whereby when the opening of the feed tube is brought intoalinement with the opening of one of the container tubes a nail at thebottom thereof will be directed into the feed tube. Seated within theupper part of the portion 2 and secured to an interior annular shoulder14- thereof by fastening screws 15 is a transverse circular plate 16supporting delivery chutes 17 leading from 'the rotary feed tubes 10 tothe delivery nozzle 3, and also a delivery chute 1S leading to thedelivery nozzle from an auxiliary feed opening 19 in the shell, thelower end ofthe tubular plunger guide being provided with openings Q0 topermit the passage of nails from said chutes to the delivery nozzle,said plate serving to cover the lower ends of all of the container tubesexcepting' the rotary feed tubes.

The casing is adapted to be closed at its upper end by a cap 2l providedwith a screw threaded portion Q2 to detachably engage a screw threadedportion 23 of the casing, this arrangement permitting the convenientloading of the magazine with nails.

Means are provided at the top of the casing for rotating', positioning'and locking the feed tubes in different positions of adjustment withtheir inlet openings in proper alinement with the outlet opening of theabove and in longi- Vof the cap.

container tubes, said means comprising'turn buttons 24, provided withshanks 25 to pass through apertures 26 in the cap 21 and be rigidlyconnected with the tops of the feed tubes to turn the same, the shanksof the Aturn buttons in the present instance are shown screw threaded attheir lower ends to engage internally screw threaded portions 2T of thefeed tubes. rIhe cap 21 is provided with slots 2S coincident with theopenings 26 to permit lugs 29 of the turn buttons to be engaged beneaththe underside vThis arrangement serving` to maintain the turn buttons inproper working positions relative to the cap. Each turn buttonisprovided with a lug 30 to engage a series of depressions 31 spacedaround the openings in the cap to facilitate the proper positioning andholding the feed tubes with their inlet openings in alinement with thevarious container tubes.

In order to control the passage of the nails from the feed tubes, aseparate feed gate or valve for each feed tube is provided to trap andhold the nails in the delivery chute. Each feed gate consists of anangle arm 32 terminating at one end in a curved or slotted cut off part33 and having at its other end a push rod 34:, said angle arm beingpivoted to the underside of the plate 16 so that the cut off portion isadapted to work through an aperture 35 of one of the chutes to catch theheads of the nails and hold them in the chute as indicated in Fig. 2 ofthe drawings. As will be understood, the nails are fed singly, the nailabove the nail in the delivery chute resting upon the head of the nailheld in the chute and being thus prevented from entering the chute untilthe feed vale is operated to release the nail in the chute. spring 36.is arranged to bear against a depending lug 37 of said plate andagainst the angle arm to normally hold the feed gate in the positionindicated. The push rod projects to the outside of the casing and isadapted to be pressed inwardly against the action of the spring to movethe cutoff portion of the feed gate to one side of the nails.

As will be understood, all of the tubes of the magazine including therotary feed tubes are loaded with nails the rotary feed tubes beingpositioned with their side openings 11 out of alinement with the outletopenings of the other container tubes, the nails being fed from eachgroup of container tubes begii'ining with the nails contained in thefeed tube, which when empty is turned to successively bring its sideopening 11 in alinement with the outlet openings of the respectivestationary container tubes of the group as required.

By providing the auxiliary feed opening 19 and the delivery chute 18, itis possible l i l to feed nails to the delivery nozzle independent ofthe magazine and its feeding mechanism.

In the present instance, I have illustrated the magazines `as being madeup of three groups of container tubes, each group comprising seventubes. It will be understood, however, that it is within the scope ofthe invention to employ a greater or less number of groups or series oftubes, each group comprising any number of tubes according torequirements. By the particular construction and arrangement of thecontainer tubes, I make it possible to shorten the length of themagazine without decreasing its capacity, and a compact construction isprovided.

What I regard as particularly important features of my invention residein the spe cial construction, combination,arrangement, and connection ofthe parts whereby the container tubes, driving plunger head, deliverychutes and delivery nozzle can be readily interchanged for other similarparts of different size or form to adapt the device for use with nailsof various sizes and forms and whereby the container tubes can bequickly removed and other parts substituted to lighten and convert thedevice into the type of tool in which the nails are separately fed byhand through an opening in the casing.

The end portion 2 is constructed as a separate part from the casing tobe detachably connected thereto, said portion being provided with athreaded part 38 for engagement with a threaded part 39 of the casing.Each delivery nozzle 3 is provided at its lower end with a threadedportion 40 for engagement with a threaded collar 41 of the portion 2,and with the threaded part 2 at its upper end for engagement with athreaded portion 42 at the lower end of the plunger guide 4:, the upperend of which is threaded to engage a threaded iiange 43 depending fromthe cap 21. The flange 43 extends slightly within the plunger guide andcoacts with shoulder portion 44 of the plunger to limit the upwardmovement of the plunger.

The circular series of tubes of each group are connected by solder orsecured together in any convenient manner, so that each group ofcontainer tubes is adapted to be handled as a whole to be removed fromor placed within the casing to rest upon the plate 1G, said groups oftubes being fixed against movement in the casing by small lugs lietconnected to the interior of the casing and the exterior of the plungerguide. The driving plunger 5 consists of a rod or stem 5'o1 to which isadapted to be connected plunger heads 5b of different sizescorrespending to the different size delivery noz# zles 3 that areadapted to be employed, the

plunger' stem being provided with a reduced threaded part 5c forengagement With threaded sockets 51 of the plunger head.

Fig. 7 illustrates verted into a tool of the type in Which the nails arefed separately by hand from the exterior of the casing, the containertubes having been removed and a Wooden casing 46 substituted for themetal casing l, said Wooden casing being provided with a reinforcingferrule at its lower end and an intermediate reinforcing band 4S.
